Description
Bisphenol S (BPS), also known as DHDPhS or 4,4'-sulfonyldiphenol, CAS 80-09-1, is a diphenol compound built around a central sulfone bridge. It carries no E-code designation. It is a recognised alternative to Bisphenol A in polymer and specialty chemical applications.
In epoxy resin and polysulfone polymer production, BPS acts as a reactive monomer, contributing thermal stability through its sulfone linkage. In personal care formulations, it functions as an antioxidant and antimicrobial agent, inhibiting oxidative degradation and microbial growth in hair dye and skin protectant systems.
BPS is supplied as a light yellow crystalline powder, with grades available to meet industrial and pharmaceutical intermediate specifications under REACH compliance. It is classified under HS code 29309070. Procurement teams should confirm supplier documentation for REACH registration status and applicable SDS before sourcing.
